Question: Why my GDI printer does not work with the
AV260C Plus?
Answer: Disable the Auto Scan function in the
application, then your printer will function in
normal working condition.
Question: Why some parallel port devices and software's
keypro do not work with the AV260C Plus?
Answer: The AV260C Plus can do pass-through printing
all right , but the pass-through printing may not
work if you connect the parallel port with
devices other than printer. Therefore, if you
would like to connect some parallel port devices
other than printer, please do not connect them to
the same parallel port that AV260C Plus
currently uses. It is suggested to use other
parallel ports to connect these devices or
keypro. For instance, you can connect the
AV260C Plus to LPT1, and connect other
parallel port devices to LPT2. Or you can add a
data switch to avoid the problem.
